THE DIVINITY RULE · THE THIRTEEN · RULE 3 OF 13
Harmony.
Branch 2 · Pythagorean Ratios
Rule 3 of the thirteen: Branch 2 · Pythagorean Ratios. It is one of the eleven principles taught openly — in a published volume on the Library shelf, and in one AI skill card that works it on your own work.
See it
THE MONOCHORD · ONE STRING, STOPPED AT A SIMPLE RATIO
The classical idea this branch is named for, to try by hand. The Rule’s own use of it is in the published volume, and in the seat.
Where it meets your work
Wherever proportion decides the work — a brand, a product, a structure, a community — the card reads its text and works Harmony on what you are making, one step at a time, and shows the measure on the work itself.
What is in the card
- SKILL.md — the door your AI reads first
- book/ — the volume itself, placed before the card sells
- CARD.md, START-HERE.md, LICENSE-NOTE.md and MY-LEDGER.md
- card.json and card.svg — its record and its face
Its text goes inside before the card is sold.

The rules before and after
The shelf is not the seat.
Reading a principle is not holding the Rule. The Divinity Rule is licensed only as THE SEAT, to one person; its practice rides only on the seat. Two principles are held for AI alone and sealed inside the seat, named nowhere.
